Application filed December 9, 1904. Serial No. 286.244.

To @ZZ whom, it' may concern:

Be it known that I, GEORGE H. VINING, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Means for ProducingFolding Matrices, of which the following is a specification.

Myinvention relates to means for producing folding matrices; and myobject is to produce paper matrices which may be folded to a convenientsize for transit through the mails or by express, By folding thematrices they can be inclosed in smaller envelops and mailed at lesscost than when they are in an unfolded condition. In producing matricesof this character means must be provided for preventing their typeimpressions from being either compressed or drawn out of shape when thematrices are folded. I provide said means in the form of folding groovesalong which the matrices are folded and supplemental grooves parallelingsaid folding grooves. The folding grooves permit easyfolding of thematrices, while the supplemental grooves take up any expansion orcontraction which may result from said folding, and consequently preventthe type impressions from becoming distorted or d-isturbed.

In the accompanying drawings, which illustrate my'invention, Figure 1represents a plan view of a form of type containing means for producingfolding matrices. Fig. 2 is a broken detail perspective view of thedevices employed for forming the folding grooves and the supplementalgrooves in matrices. Fig. 3 is a broken vertical section taken on lineIII of Fig. 1, showing the manner in which the outer end of one of mydevices is held in position in the form of type. Fig. 4 is a detailperspective view of a matrix provided with folding grooves andsupplemental grooves formed with my devices. Fig. 5 is an end view of amatrix folded made in accordance with my invention. Fig. 6 is a brokenmodication of one of my devices for producing perforations instead ofgrooves in the matrices.

In said drawings, 1 designates a chase provided at one end withadjusting-screws 2 and 3, respectively, the latter of which bearsagainst one end of a quoin 4, located at one side of the chase, whilethe former bears against one side of a foot-bar 5, located at one end ofsaid chase. 6 designates a head-bar bearing against the innersurface ofthe opposite end of the chase. Both of said bars are provided. at theirunder sides with transverse grooves 7 and 8, respectively, the grooveson one bar being arranged in alinement with those on the other for thereception 0f the reduced ends 9 of columnrules 10, employed in spacingtypes A in the usual manner. Said types are forced into close contactwith each other and the columnrules by means of quoin 4 and foot-bar 5,which are operated by adjusting-screws 2 and 3.

All of the above parts except head-bar 6 are in general use and requireno further explanation.

My devices for producing folding matrices comprise three members 11, 12,and 13, arranged in the form of a cross, dividing the columns of typeinto four equal portions, as shown in Fig. 1. Member 11, which is oblongin cross-section, is arranged transversely in the chase and provided atits upper surface with a centrally-disposed longitudinal rib 14 and twomarginal ribs 15, paralleling rib 14. All of said ribs are of inverted-Vform in cross-section, as shown in Fig. 2. Rib 14 is slightly higherthan ribs 1.5 and more than type-high in order to form a transversefolding groove 14a in matrix 16, along which the latter may be readilyfolded. Ribs 15 form supplemental grooves 15u in the man trix, whichtake up all expansion and contraction resulting from folding saidmatrix, and thus prevent the distortion of the type impressions in thelatter. Member 12,which is similar in shape to member 11, is slightlywider than the latter and. abuts at its inner end against same, whileits outer reduced end 12"L underlaps the central grooved portion of thefoot-bar, as shown in Figs. 1 and 3. Said member 12 is provided at itsupper surface with a centrally-disposed longitudinal rib 17 and twomarginal ribs 18, paralleling rib 17. Rib 17 is slightly longer at oneend than its companions in order to abut against rib 14, a notch 15bbeing left in the adjacent rib 15 for this purpose, and is equal inheight to rib 14, so that it will form a folding groove 17a,communicating with groove 14a in the matrix.

IOO

Ribs 18 form supplemental grooves 18a in the matrix, which like grooves15 take up all expansion or contraction resulting from folding saidmatrix the second time. Ribs 17 and 18 like ribs 14 and 15 are ofinverted-V form in cross-section. Member 13 is of equal thickness andarranged in alinement with member 12. It has a reduced end 13aunderlapping the grooved central portion of head-bars 7 and abuts at itsinner end against one side of member 11 as shown in Fig. 1. It isprovided at its upper surface with a pair of longitudinal ribs 19 andtwo marginal ribs 20,

aralleling the former. Ribs 19 are slightly onger at one end than theircompanions in order to abut a ainst rib 14, notches 15c being left inthe a jacent rib 15 for this purpose. The up er surfaces'of ribs 19 areflush with those o ribs 14-17 in order to form a pair of folding grooves19a in the matrix communicating with groove 14. Ribs 20 formsupplemental grooves 20a in the matrix, which assist grooves 18a intaking up any expansion or contraction resulting from folding the matrixthe second time. By providing the matrix with a pair of folding grooves19a the four thicknesses 16EL formed by folding the matrix the secondtime will lie close together, as shown in Fig. 5.

21 designates a air of illing-strips interposed between We ge 4 and theadjacent column-rule to prevent said wedgefrom contacting with theadjacent end of member 11, and thus preventing the latter from movinglongitudinally with the type when screws 2 are adjusted inwardly.

By introducing head bar 6 and fillingstrips 21 into the form members 11,12, and 13 will not interfere with the operation of forcing the typesinto close contact with each other and the column-rules, because grooves8 in the head-bar permit the column-rules to move forward until thetypes have been forced tightly into contact with each other and saidhead-bar, while the lling-strips prevent the quoin from contacting withthe adjacent end of member 11 when said quoin is expanded to force thetypes tightly into contact with each other and the columnrules.

When preparing small matrices requiring but a single fold, members 12and 13 are dispensed with.

If desired, the folding ribs and supplemental ribs may be dispensed withby providing the devices with rows of studs 227 as shown in Fig. 6. Saidstuds may be of sufficient length to penetrate the matrix; but ifdepressions are found in practice to answer the purpose said studs willbe made shorter than the thickness of the matrix.

A matrix made upon a form like that shown in Fig. 1 may be cut into fourparts preparatory to casting stereotype plates therefrom, or, ifpreferred, the stereotypeplates may be cast from the complete matrix andthen either sawed along the grooves or parallel therewith.

While I have shown but three members in the present drawings containinggrooveforming elements, it is obvious that this number may be increasedor diminished in accordance with the number of times it is desired tofold the matrices. I also reserve the right to make such changes asproperly fall within the scope of the appended claims.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. The combination with a form of type, of a member arranged in saidform, and a series of ribs on said member for rendering matricesfoldable.

2. The combination with a form of type, of a plurality of memberssuitably arranged in said form, and means on said members arrangedparallel to each other for rendering matrices foldable.
